Structural Valve Deterioration

A 34-year-old woman was hospitalized with shortness of breath and chest tightness and pain. She had undergone aortic valve replacement for aortic stenosis at the age of 18 years. Transthoracic echocardiography showed left ventricular asynergy and a high aortic valve pressure gradient. Thus, structural valve deterioration was diagnosed. Coronary computed tomography and coronary angiography revealed left main trunk ostial stenosis that had caused acute anteroseptal myocardial infarction. Urgent surgery revealed pannus formation around the prosthetic valve and covering the ostium of the left main trunk. A Bentall procedure and coronary artery bypass grafting were performed. The postoperative course was uneventful.

Transcatheter Aortic Valve

Coronary obstruction, a rare complication of transcatheter aortic valve replacement, can be fatal. Few data exist on this phenomenon, and, to date, authors have reported only single coronary lesions. We present a case in which 2 coronary arteries obstructed immediately after transapical transcatheter aortic valve replacement. The patient was an 81-year-old woman with symptomatic severe aortic stenosis who underwent transapical transcatheter aortic valve replacement. Immediately after an Edwards Sapien XT valve was deployed, she experienced sudden cardiogenic shock resulting from obstruction of the left main coronary artery ostium and the distal left anterior descending coronary artery. The left main obstruction was caused by direct compression from a large calcified mass and the valve frame. The left anterior descending coronary artery obstruction was caused by ambient myocardial tightening and external compression around the apical sutures. Revascularization was achieved through coronary stent placement and suture removal, respectively. Our patient's case highlights the risk for coronary obstructions after transapical transcatheter aortic valve replacement, and we discuss how they can be managed.

Transcatheter Aortic Valve

Complications resulting from the delayed clinical presentation of a left main coronary artery obstruction can be catastrophic. This case report presents a 73-year-old woman with severe aortic stenosis who underwent transcatheter aortic valve replacement with a core valve who, approximately 20 minutes after heparin reversal with protamine, became hypotensive and was unresponsive to vasopressor and inotropic therapy. Transesophageal echocardiography demonstrated global hypokinesis, which was highly consistent with the occlusion of the left main coronary artery. Angiography confirmed this diagnosis and demonstrated that valve positioning had not changed compared to post-placement examination. Here we report the partial covering of the ostium of the left main coronary artery by a core valve skirt that converted into a total occlusion following the initiation of heparin reversal with protamine and the value of multimodal imaging in the management of this case.
